PROBLEM TO BE SOLVED: To solve problems of: limited driving accuracy caused by disturbance generated in driving by pulling a heavy and thick power supply cable in performing drive control of an AZ rotary structure (rotor) of an antenna for satellite communication or a telescope in a mode where the rotor rotates 270° in tracking a celestial body or a mode where the rotor turns within a predetermined angle range in tracking a satellite; and difficulty in power supply in the case of an electric wave power supply system which cannot transmit an electromagnetic wave so as to follow movement of a plurality of power reception units arranged on the rotor or a mobile body.SOLUTION: Two or more power transmission units are installed on an installation surface, and a plurality of power reception units are arranged on an AZ rotary structure on which drive control is performed. When a moving power reception unit is included within a coverage area of an electromagnetic wave transmitted by each power transmission unit, the power reception unit receives the electromagnetic wave and supplies power to an EL drive unit, power consumption unit, and the like. The power transmission unit further acquires transmission direction information by receiving drive control data from a drive unit or a pilot signal transmitted by the power reception unit, and radiates an electromagnetic wave toward a calculated transmission direction. |
